Dawn grassroots association obasanjo says joins coalition movement

I think there may be a few issues with the sentence you provided.

Firstly, "dawn grassroots association" doesn't seem to be a real organization. It's possible that you meant to say "Dawn Grassroots Association" or something similar.

Secondly, "obasanjo says" is a phrase that implies that someone named Obasanjo is making a statement. However, without more context, it's unclear who Obasanjo is or what his relationship is to the Dawn Grassroots Association.

Lastly, "joins coalition movement" is a phrase that implies that the Dawn Grassroots Association (or Obasanjo, if that's who you meant) is joining a pre-existing coalition. However, without more context, it's unclear what coalition you're referring to or what the purpose of the coalition is.

If you could provide more information or clarify what you mean, I'd be happy to try and help you with your question!
